Welcome to our new doctoral students Sara Amido, Sebastian Buchczyk, Jialing Liang, Clàudia Martínez, and Aida Villaécija! A belated welcome also to Beatriu de Pinós postdoc Salvatore Pistoia-Reda, who joined us just before the confinement in March. And welcome also to David Bordonaba Plou, visiting us for the fall from the Universidad de Valparaíso, and Isidora Stojanovic, who will be a visiting researcher for the coming year.
